What is the real danger of using receptacles with loose spring tension fingers?

Using receptacles with loose spring tension fingers presents a significant risk of wiring burning back into the conduit. This is primarily due to poor contact between the receptacle and the plug of the device being connected. When the connection is not secure, it can create resistance at the point of contact. This resistance generates heat, which, over time, can cause the insulation on the wiring to deteriorate, leading to potential burnout or arcing. If continuous heat builds up, it can cause the wires to burn back into the conduit, resulting in fire hazards or equipment failures.

While electrical shock, insulation failure, or increased energy consumption are valid concerns in electrical systems, the specific threat posed by loose spring tension in receptacles relates directly to the risk of overheating due to inadequate contact. This can lead to catastrophic failures, making the identification of this risk crucial for proper electrical safety and maintenance.
